The engine is the most important of the car systems. Without it, there is no movement and therefore no car. By analogy with a structure of the person, it is the heart of the car.
According to its purpose, the motor is a source of mechanical energy needed to drive the vehicle. In order to obtain mechanical energy, another type of energy (combustion energy, electrical energy, etc.) is converted into the car motor. The energy source must be located directly in the car and periodically replenished.
The transfer of mechanical energy from the motor to the drive wheels is carried out via the transmission. The structural combination of motor and transmission has an established name of the power plant.
- The first basic type is a piston motor. The combustion chamber is a cylinder where the chemical energy of the fuel is converted into mechanical energy, which is converted from reciprocating motion of the piston into rotary motion by means of a crank-rod mechanism.
- The other is the rotary piston one.
By the type of fuel used motors are divided into gasoline, diesel and combined.
For normal engine operation, the cylinders must be fed with combustible mixture in a certain proportion (for carburetor engines) or measured fuel portions at a strictly defined moment under high pressure (for diesel engines). To reduce the cost of friction, heat dissipation, scoring and rapid wear, rubbing parts should be lubricated with oil. The engine must be cooled down in order to create normal thermal conditions in the cylinders. All engines installed in cars consist of the following mechanisms and systems.
How much does it cost to rebuild an LS1?
If the original SBC has defined the development for V8 with the camshaft in the cylinder block, the LS-series have moved in this direction to a whole new level. The 16-valve archaic V8 was simply unable to compete with modern DOHC engines, but the lightweight and compact LS made it possible for the fifth and sixth generation to become a world-class sports car without any reservations.
The first engine in the LS-series range was introduced to the fifth-generation Corvette (C5) in 1997. It was an all-aluminum bottom eight with electronic fuel injection, which received the index LS1. The following year, the LS1 replaced the cast iron LT1 from under the hoods of Chevrolet Camaro and Pontiac Firebird. The LS1 had a classic volume of 5.7 liters and 345 hp in the factory version. In 2005, the fourth generation of LS-series was released, which differed from the third by a larger volume, more efficient timing and optional partial cylinder shutdown system to reduce fuel consumption in a quiet mode of the engine.
We are interested in the most powerful representatives of Gen IV, namely LS2 (6 hp, 400 hp), LS3 (6.2 hp, 430 hp), LS7 (7 hp, 505 hp), as well as LS9 (6 hp, 638 hp) and LSA (6.2 hp, 580 hp), equipped with a mechanical supercharger. These motors were installed in different versions of Corvette, Camaro and Cadillac CTS-V, depending on the output.
It was thanks to LS-series that America was able to compete with European high-tech engines. Today, the engines of LS-series can be found everywhere – on the chassis of a classic American pickup truck of the 50s somewhere in Sweden, and in Nissan Silvia on the New Zealand stage of drifting series D1.
An LS rebuild with stock parts will cost you around $2,000 to $3000, buying a rebuilt LS1 or LS2 will be around $3500, and a new LS1 motor will run you a little over $4000 (like Chevy engine rebuild kits).
How much does it take to rebuild an LS engine?
If you are not content with your motor performance, you can bring it back to life with a rebuild kit. There are two main reasons why you’d want to rebuild a motor. They are the wear to motor bearings, and poorly seating piston rings. Kits help the buyer to buy all needed parts at a lower price.
The final price will depend on malfunctions. Rebuild with stock parts is probably going to cost you around $2,000 to $3000.
What is included in an engine rebuild kit?
There are many things that you can do to return the powerful character of your motor. You can get certain upgrades like a higher-performance intake or exhaust. You can mount power-enhancing add-ons like a spoiler. Or, you can benefit from getting an engine rebuild kit. A kit is a full package that consists of such parts as pistons, cams and lifters, as well as smaller hardware like pistons rings and seals. It is perfect for restoring a worn and ageing engine.
How much does it cost to rebuild the bottom end?
Bottom end replacement is usually required for mechanical damage to the underside of the engine. It should be noted that the ICE crankcase, due to its location, requires additional protection. Plates made of steel, aluminum or composite materials can be found.
Replacing a motor crankcase pallet may also be necessary for non-critical damage. For example, deformation of the part will not allow the pallet to remain tight, resulting in constant lubricant leaks.
The bottom end rebuild usually means an overhaul. It can cost you around $2000-$4000.
